Wellbore Fluids Comprising Mineral Particles and Methods Relating Thereto

A wellbore drilling assembly comprising:

• a pump in fluid communication with a wellbore via a feed pipe;
• a drill string with drill bit attached to the distal end of the drill string;
• and
• a wellbore fluid in contact with the drill bit, wherein the wellbore fluid comprises a base fluid and a wellbore additive, the wellbore additive comprising:
• a plurality of first mineral particles having a specific gravity of about 2.6 to about 20;
• a plurality of second mineral particles having a specific gravity of about 5.5 to about 20;
• a plurality of lubricant particles having a specific gravity of about 2.6 to about 20;
• wherein the first mineral particles, the second mineral particles, and the lubricant particles are different;
• and
• wherein the first mineral particles, the second mineral particles, and the lubricant particles have a multiparticle specific gravity of about 3 to about 20.

A wellbore drilling assembly comprising:

• a pump capable of introducing a fluid into a wellbore via a feed pipe;
• a fluid processing unit capable of receiving the fluid from a wellbore via an interconnecting flow line;
• and
• a wellbore fluid disposed in at least one selected from the group consisting of the pump, the feed pipe, the wellbore, the interconnecting flow line, the fluid processing unit, and any combination thereof, wherein the wellbore fluid comprises a base fluid and a wellbore additive, the wellbore additive comprising:
